一つ目の記事に書いてあることはCake2.*でもそのままつかえます。ファイルの場所が 'app/libs/log/database_logger.php'(for CakePHP 1.*) から 'app/Lib/Log/Engine/DatabaseLog.php' (for CakePHP 2.*)になるぐらいです。素晴しい。

たとえばログにセッション情報(ユーザＩＤとかね)を記録したい、みたいな事になったら、ユーザがログインしてるのか確かめないと、ログインしてない時に上手くログに入りません。例えばログイン失敗しました、みたいなログがきちんと取られないことになります。

public function write($type, $message) {
 $log['type'] = ucfirst($type);
 $log['created'] = date('Y-m-d H:i:s');
 $log['content'] = $message;
 if ($login = CakeSession::read('Auth.User')) {
  $log['user_id'] = $login['id'];
 }


 return $this->Log->save($log);
}

[CakePHP2]Database logging (with some Cakesession Object)

Well, Jan's article is totally usable even in CakePHP 2.4 except one location 'app/libs/log/database_logger.php'(for CakePHP 1.*) to 'app/Lib/Log/Engine/DatabaseLog.php' (for CakePHP 2.*).

When you want log some information via Cakesession Object (i.e. user ID), you should check the object first in case the user not logging in.

public function write($type, $message) {
 $log['type'] = ucfirst($type);
 $log['created'] = date('Y-m-d H:i:s');
 $log['content'] = $message;
 if ($login = CakeSession::read('Auth.User')) {
  $log['user_id'] = $login['id'];
 }


 return $this->Log->save($log);
}
